Accurate professional scale for quick control of wear (extension) of the bicycle chain. Different measurement principle than most other scales. The position of the first contact is fixed by pressing the chain roller against the chain pin as when stressing the chain by pulling on the teeth of the converter / pinion. The calibration touch is graduated and indicates 0% (mesh), 0.5% (limit for 11-12speed chains) and 0.75% (limit for 5-10speed chains) wear. Compatible with 5-12speed chains (including SRAM AXS). Made of stainless steel in the USA
